AmethystEffects & Experience
Reported effects center on creative, calm. Amethyst pulls toward a balanced state where neither head nor body dominates — a profile that holds up across phenotypes when the seeds are grown to their potential.
Growing Amethyst
Growing Amethyst fits outdoor growers with at least 130 frost-free days; the balanced structure handles both heat and cool nights. Amethyst is photoperiod, which means you control when it flowers by switching from 18/6 (vegetative) to 12/12 (flowering). Most indoor growers veg for 4-6 weeks before the flip. Indoor yields land around 450-550 g/m² under quality LED, and outdoor plants given full sun and 5-7 gallon containers reliably produce 500-700 g/plant. Expected plant height is 120-180 cm, with intermediate cultivation difficulty. Practical tips that move the needle: maintain canopy airflow with an oscillating fan moving air through the leaves, not just above them, to prevent powdery mildew; and feed cal-mag from week 2 onward at 2-3 mL per gallon — most reverse-osmosis and soft tap water setups need it. The most common challenge growers report is over-feeding nitrogen past week 1 of flower — switch to bloom nutrients within 7 days of seeing pistils.
